✦ Synopsis

The double intramolecular radical induced reaction of 5 gives in a highly regioselective reaction via a 7-endo mode the tricyclic silaalkane 7 in 42% yield. In addition. The bicyclic trisilane 8 also formed by a 7-endo cyclisation, is obtained in 33% yield. The structure of 7 has been confirmed by X-ray structure analysis.
